Use the system dimming for standalone widget picker activity, as the system
is applying a default transition.

Pin widget sheet should open from bottom up and close on drag down.
Behaviour with navigation bar is similar to that of widgets bottom sheet.
Add a drag layer and reuse AbstractSlideInView for open-close
animation.
Test: Tested manually- opening, closing through dragging/ cancel button/
back button. Adding widget to screen by dragging/ add to home screen
button.
